Various image-capturing systems are disclosed that use polarized filters
to reduce or control glare effects on captured images. In one embodiment,
the system includes a light source, a first polarized filter adapted to
polarize light emanating from the light source; a second polarized filter
adapted to perform polarized filtering on received light; and an
image-capturing device adapted to receive the filtered light. In another
embodiment, the system further includes an actuator to selectively move
any of the polarized filter into and out of the light path. In yet
another embodiment, a method of forming a resultant image comprises
recording a first image with a filter set to a first polarization angle,
recording a second image with the filter set to a second polarization
angle, and blending the first and second images. The recording of the
first and second images may be performed simultaneously or at different
times.
